Abstract
An audio analysis apparatus includes the following components. A strap has an end portion connected to a main body and is used to hang the main body from a user's neck. A first audio acquisition device is at the end portion or in the main body. Second and third audio acquisition devices are at positions separate from the end portion by substantially the same predetermined distances, on the respective sides of the strap extending from the user's neck. An analysis unit discriminates whether an acquired sound is an uttered voice of the user or another person by comparing audio signals of acquired by the first and second or third audio acquisition devices and detects an orientation of the user's face by comparing the audio signals acquired by the second and third audio acquisition devices. A transmission unit transmits the analysis result to an external apparatus.
